The elevation oftliis tube is readily accomplished bypivoting to the collar 2O a bifurcated leverV 22, the pair of arms 2.3of whichembrace the outer end of the ytube 'and serve as cams to engagethe bottom of the housing for lifting said fill tube when the outer armportion of Vthe lever is The outer end 24C of each cam arm 23 is more orless flattened so that when the arms 23 are broughtto a verticalpositionlever 22 is substantially V'xed and the tube is supported through thearms 23 contacting with the bottom of the housing 18, as indicated in Fig. 2 of the drawings. In this position, also, the outer end of Ytube 11is brought into close proximity to the top of the housing so that vthefilling nozzle 2l Amay conveniently be inserted therein; and thisnozzle, furthermore, servesto obstruct the vreturnof the tube 11tliiiough'contact with the lever 22.

When the filling operation is concluded and thenozzle 21 withdrawn,lever -22 is turned over to theiposition .indicated in/Fig. 3 of thedrawings wherein it lies substantially along the bottom of the housing.Tube 11 is'thereby returned to its normal position wherein its innermostend contacts with the bottom of thetan'k 10; and, in order to preventunauthorized hlling, provision is made to lock or seal the said lever sothat the tube may not be elevated except by an authorized agent. This isconveniently accomplished by providing the louterrend of lever 22 withan opening orV perforation 25 which is adapti ed,`when the lever is inthe position indicated in Fig. 3,y to register with a similarperforation 26 of a vlugp27 directed inwardly from the wall of housing13.
